QA·C Help - 1258

	1258	Suffixed integer constant cast to a different integral type.

Arithmetic type - Casts

An integer constant is being cast to a different integral type. Is this intended ? Perhaps the suffix is inappropriate ?

Message 1258 is generated if the constant is suffixed. Message 1259 is generated if the constant is unsuffixed. Neither message is generated if the cast is to a type of lower rank than int.

For example:
